I believe that we have not been comparing Lucas Perez to the right set of players. Here are his numbers versus Mahrez. His stats are quite identical to the Algerian's, showing a man who is adept at both scoring and creating. I suspect he's been the alternative to Mahrez, not a striker. He has primarily played as a left winger in his career, with a more recent focus on centre forward.Â
If we do use him with Giroud, then on which side would Perez and Sanchez be deployed to get the most of them?
